ABSTRACT Objective Structured Clinical Examinations (OSCEs) are widely used to assess medical students clinical skills, including non-technical abilities such as communication and empathy. However, the potential influence of individual psychological traits, such as personality dimensions, empathy, and stress-related mindset on OSCE performance remains understudied. This study investigated associations between personality traits, empathy levels, stress mindsets, and performance in OSCEs among medical students. An online questionnaire (including the Big Five Personality Traits Inventory 2, the Jefferson Scale of Physician Empathy (Medical Student version), the Growth Mindset Scale, the Stress Mindset Measure) was provided to all fifth-year medical students enrolled at the Universite Paris Cite for six weeks before undertaking graduation summative OSCEs. Their scores were correlated with OSCE performance using Spearmans correlation and linear regression analyses. A total of 99 questionnaires were included and analysed. None of the psychometric tests we assessed showed a significant correlation with OSCE scores. The strongest predictors of success in OSCEs were higher scores in written examinations, previous OSCE performance, and being female. In non-interactive OSCE stations, conscientiousness was the only significant predictor, with a positive association (p=0.001). Neuroticism was positively associated with performance improvement between OSCE sessions (p=0.042). Personality traits, self-reported empathy, and stress-related mindsets do not predict success in OSCEs as isolated traits. Further research is needed to determine whether it holds true for all kinds of OSCEs. Multidimensional psychometric assessment may be relevant when investigating performance outcomes in OSCEs.

Background: Increasing relevance of genetics and molecular biology in medicine necessitates greater genetic literacy among healthcare workers. To assess the literacy level, a validated genetic literacy questionnaire is needed. Therefore, a standardised Indonesian-language genetic literacy questionnaire is essential. Aims: We aimed to translate and validate three genetic literacy questionnaires (PUGGS, iGLAS, and UNC-GKS) for use among Indonesian medical students. We then evaluated genetic literacy levels using one of the validated questionnaires. Methods: The PUGGS, iGLAS, and UNC-GKS questionnaires were translated into Indonesian and then reviewed by an expert panel for translational accuracy and conceptual appropriateness. Back-translation was performed to confirm validity. Initial Indonesian versions of the questionnaires underwent cognitive pre-testing with 12 undergraduate medical students. After refinements, the questionnaires were validated among 34 first- to third-year medical students. The Indonesian version of UNC-GKS questionnaire was then used to assess genetic literacy of 486 medical students comprising 228 preclinical medical students, 187 clerkships, and 71 residents. Results: The Indonesian versions of PUGGS (Cronbach's = 0.819) and UNC-GKS ( = 0.809) demonstrated good reliability, while iGLAS showed poor reliability ( = 0.315). Among the 486 students tested, 56% demonstrated moderate overall genetic literacy, and only 15.2% demonstrated good overall literacy. Basic genetic concepts were relatively well-understood with 54.3% having good literacy. On the contrary, gene variant's effects on health were poorly understood with only 9.7% having good literacy. Inheritance concepts were moderately understood with 24.9% having good literacy. Conclusion: The Indonesian translations of PUGGS and UNC-GKS are reliable tools for assessing genetic literacy among medical students. Using UNC-GKS, we observed predominantly moderate genetic literacy levels. Curriculum improvement to better integrate genetics education is essential to support its clinical applications.

Background Conventionally, infertility has been regarded as primarily a female issue, leading to misconceptions, stigma, and underrepresentation of male infertility in healthcare discussions. This study assessed the knowledge, attitude and perception of Undergraduates towards male infertility in Osun State University. Methods A descriptive cross-sectional design was employed to select 300 undergraduates via multistage sampling. Qualitative data were collected using a focus group discussion guide covering the knowledge, attitude and perception, while quantitative data were collected using a self-administered questionnaire covering socio-demographic characteristics, knowledge, attitude and perception towards male infertility. Qualitative analysis was performed using NVivo software, while IBM SPSS Statistics version 27 was used for the quantitative analysis, with thematic analysis and chi-square tests to determine the association between variables (significance at p < 0.05). Results Respondents were predominantly females (64.0%) with a mean age of 20.99 {+/-} 2.31 years. Overall knowledge was low (47.7%), while more than half had a negative attitude (52.3%). Significant predictors of attitude include faculty (0.049), level (p=0.031), and formal education on male infertility (p=0.007). Conclusion Students demonstrated a poor understanding of male infertility, and their attitudes remain influenced by cultural norms surrounding marriage, masculinity, and gender roles. Hence, the need to foster open dialogues, promote gender-inclusive narratives, and strengthen healthcare support systems.

BackgroundHigh workload among healthcare workers has increasingly been correlated with poor patient outcomes, inefficient operational and financial outcomes, and burnout. Despite growing literature exploring causes of attending physician workload, there is limited understanding of trainee-specific measures. ObjectiveWe aimed to characterize elements contributing to trainee workload and perceived challenges and satisfiers to the trainee workday as a foundation for better understanding and measuring trainee work experience. MethodsInternal Medicine and Medicine-Pediatrics residents at an academic medical center were invited to participate in focus groups discussing contributors to inpatient workload and work experience between March and April 2024. A qualitative content analysis identified key metrics of trainee workload and work experience, which were then consolidated into overarching domains. A structured, multi-round rating process ranked the perceived relevance of each metric. ResultsTwenty residents participated across six focus groups. Analysis of focus groups yielded 297 workload metrics across 28 unique domains. Seventeen domains had metrics identified as highly relevant (median 6-7; IQR < 1) including autonomy, communication, disruptions, task switching, documentation, emotional burden, patient factors, professional fulfillment, rounding, teaming, and work-life balance. ConclusionsResident physicians highlighted complex interactions between clinical factors, work design, and psychosocial dynamics that contribute to their sense of workload. This creates opportunities to develop unique measures of workload to understand the trainee experience better. Further studies are needed to capture the generalizability of these findings and the relationship between these workload domains and patient, organizational, and trainee outcomes with the aim of implementing evidence-based work design.

Background: Palliative care services improve quality of life and health outcomes for individuals living with chronic and life-limiting illnesses. Although these services have expanded considerably in urban areas, their availability remains limited in many rural communities. This study aimed to identify key components of integrated palliative care services and examine how these elements are implemented within rural healthcare systems in southern Minnesota. Methods: A qualitative case study using deductive content analysis was conducted. Semi-structured interviews were carried out with healthcare professionals involved in palliative and hospice care serving rural communities in southern Minnesota. Results: Participants identified several essential components of integrated palliative care, including multidisciplinary care teams, continuity of care across healthcare settings, interprofessional collaboration, and early identification of patients who may benefit from palliative care. Existing services in southern Minnesota incorporate several integrated elements, such as coordinated care teams, individualized care plans, nurse-led case management, professional training, and the use of virtual visits for geographically distant patients. However, participants also identified important gaps, including limited availability of palliative care services in rural areas, fragmented continuity of care, challenges in early patient identification, funding and insurance barriers, and the absence of a unified palliative care network. Conclusions: While palliative care services in southern Minnesota demonstrate important strengths, further efforts are required to improve service integration, coordination, and access for rural populations. Strengthening integrated PCSs may help reduce disparities in access to care and improve service delivery for rural patients and their families. These findings may inform the development of integrated palliative care models in rural healthcare systems beyond the study setting.

BackgroundPeriodontal disease (PD) and diabetes mellitus (DM) have a well-established bidirectional relationship, affecting glycaemic control and chronic disease outcomes. However, the extent to which medical training supports physician awareness of this association remains unclear especially in resource-limited settings. ObjectiveTo assess exposure to oral health education and to identify predictors of awareness of PD-DM association among physicians. MethodsA cross-sectional study was conducted among 146 physicians managing diabetic patients at a tertiary teaching hospital in Ghana. A structured questionnaire assessed exposure to oral health education, periodontal disease knowledge (score range 0-5), and awareness using a 5-item Likert scale (score range 5-25). Multivariable linear regression identified predictors of awareness. ResultsAlthough 62.1% reported exposure to oral health content during undergraduate training, 59.2% rated its quality as poor. Mean awareness score was 20.6 (SD=2.8). Awareness was independently predicted by years of professional experience (p < 0.001) and periodontal disease knowledge (p = 0.008), but not by structured oral health curriculum exposure. ConclusionAwareness of the PD-DM link was high but was not explained by formal educational exposure. Awareness appears to develop through knowledge of PD and professional experience, suggesting a gap between curricular exposure and competency.

Global healthcare is targeting patient-centred care, as it leads to better health outcomes and higher level of patient satisfaction. Patient-centred communication, is an important part of patient-centred care because it focuses on involving patients in their care. Recent surveys both nationally and globally have shown that patients are not involved enough in their own healthcare decisions. This problem is especially common among the elderly with chronic conditions. This study aimed to describe patient-healthcare professional interactions, expectations, and satisfaction in physiotherapy within an understudied context, thereby providing important, specific data on ICE dynamics and satisfaction in the specific setting. Cross-sectional study of participants in scheduled consultations was conducted. Two government physiotherapy centres, seven private physiotherapy centres and two trust centres with physiotherapy facilities in Gujarat, India. 232 patients (from various public and private physiotherapy clinics) participated in the study. Patients' ideas, concerns, expectations (ICE) and satisfaction were explored. Almost 88% of patients reported their thoughts and explanations about their symptoms during the consultation. Most patients described not having any concerns about the diagnosis/treatment, and more than two-third of patients consulting PTs expected explanation for their symptoms. Almost 90% patients were satisfied with the consultation. The study revealed that while most patients conveyed their thoughts during consultations, very few expressed their concerns. Overall, patients were satisfied with their consultations.

ABSTRACT Background: Student nurses satisfaction with their academic programme is crucial for measuring the success of nursing training institutions. However, in Ghana, studies on student nurses' satisfaction have mainly focused on clinical learning, neglecting their satisfaction with the academic programme as a whole. This study therefore, assessed the predictors of student nurses satisfaction with their academic programme. Methods: A quantitative cross-sectional study design was used in the study. A systematic random sampling technique was employed to recruit 241 student nurses from two Nursing Training Institutions in the Eastern Region of Ghana. The Nursing Student Satisfaction Scale (NSSS) was used for data collection and data was analyzed using Statistical Package for Social Sciences (SPSS) version 27 software. Results: Correlation analysis revealed significant positive associations between satisfaction with curriculum (r = 0.583, p<0.001), faculty role (r = 0.650, p<0.001), social interaction (r=0.680, p<0.001), and overall satisfaction with the academic programme. After adjusting for the school of the student nurses, the school environment (B=0.354, p =0.000) and social interaction (B=0.291, p=0.001) emerged as significant predictors of student nurses' satisfaction with their academic programme. Conclusion: The study highlights the need for interventions to enhance the school environment and foster positive social interactions to improve student nurses satisfaction with their academic programme.

Abstract The ISBAR framework is used to standardize clinical handovers and enhance patient safety. Observational tools based on ISBAR have been developed to assess the completeness of information transfer. However, these instruments have primarily been developed in non-Chinese contexts, and validated Chinese-language observational tools suitable for clinical practice remain limited. In this study, a cross-cultural adaptation and psychometric validation of the ISBAR Structured Handover Observation Tool was conducted, examining its reliability and discriminant validity in Chinese clinical settings. The study was conducted in two phases: cross-cultural adaptation and psychometric evaluation in real-world clinical settings. Content validity was assessed using the Content Validity Index (CVI), and inter-rater reliability was evaluated using the Intraclass Correlation Coefficient (ICC) based on a two-way mixed-effects model with absolute agreement. Discriminant validity was examined using the Mann-Whitney U test to compare scores across nurses with varying levels of clinical experience. A total of 233 handover cases involving patient transfers from the intensive care unit (ICU) to general wards were collected, involving 84 nurses. The scale demonstrated good content validity, with item-level content validity indices (CVI) ranging from 0.88 to 1.00 and a scale-level CVI/Ave of 0.98. The inter-rater reliability, assessed using fifty randomly selected cases, was high, with an intraclass correlation coefficient (ICC) of 0.885 for single-rater assessments and 0.939 for average-rater assessments. Discriminant validity analysis showed that nurses with more clinical experience had significantly higher total scores than those with less experience (Z = -4.772, p < 0.001). The Chinese version of the ISBAR Structured Handover Observation Tool demonstrates good content validity, high inter-rater reliability, and acceptable discriminant validity. This tool provides a standardized and practical method for assessing the completeness of information transfer and is expected to support quality improvement in patient handover from the ICU to general wards in Chinese clinical settings.

Background: China has implemented policies to strengthen its pharmacist workforce since the 2009 healthcare reform, yet a comprehensive evaluation of their long-term systemic effects is lacking. Objective: To systematically analyze the evolution of Chinas pharmacist workforce in healthcare institutions from 2007 to 2023 across four dimensions: quantity, quality, structure, and distribution, providing an empirical foundation for policy optimization. Methods: A retrospective analysis was conducted using longitudinal data from the China Health Statistics Yearbooks. Trends were delineated via descriptive statistics. Equity and spatial evolution were assessed using the Gini coefficient, Theil index decomposition, and spatial autocorrelation analyses (Global Morans I and hotspot analysis). Results: From 2007 to 2023, the total number of pharmacists increased from 357,700 to 569,500 (average annual growth: 2.2%). This growth lagged behind physicians (4.6%) and nurses (7.4%), causing the pharmacist-to-physician ratio to decline from 1:5.15 to 1:8.39. The workforce showed trends of feminization (female proportion rose from 59.7% to 70.8%) and aging. While quality improved, 51.1% still held an associate degree or below, and only 6.6% held senior titles. Equity analysis revealed the provincial Gini coefficient improved from 0.145 to 0.093. Theil index decomposition confirmed intra-provincial disparities as the primary inequality driver. Spatial analysis showed a non-significant global Morans I by 2023 (0.154, P*>0.05), down from 0.254 (P<0.01) in 2007. Hotspot analysis confirmed this transition, revealing a contraction of high-confidence clusters and a trend toward balanced distribution. Conclusions: China has made measurable progress in expanding pharmacist workforce size and improving inter-provincial equity since 2007. However, persistent structural challenges remain: relative workforce contraction compared to other health professions, an aging demographic, a shortage of senior talent, and significant intra-provincial inequity. Future policies must prioritize optimizing workforce structure and enhancing clinical service capabilities to catalyze a shift toward patient-centered pharmaceutical care.

Objective: To investigate, in the context of endometriosis management, the perceptions of patients and healthcare professionals regarding hormonal treatment options. Design: Qualitative study using semi-structured focus group methodology. Setting: University hospitals and academic research center. Subject(s): Patients with endometriosis (n=20) and healthcare professionals (n=13) involved in their care. Intervention(s): Not applicable Main Outcome Measure(s): Focus group topics investigated representations on the concept of treatment effectiveness, emotion associated to this medical management and the perceived impact of these therapies on patient-professional and patient-environment relationship. Result(s): We highlighted a discrepancy between patients and doctors regarding the concept of efficacy of hormonal therapies. Long-term amenorrhea is the main priority for healthcare professionals, whereas pain reduction remains the immediate wait for patients. Interviewed patients reported a lack of listening and empathy, a shared-information deficit as regards treatment options and side-effects and a need to involved partner and family in care. These factors contribute to communication issues between patients and doctors and appear to contribute to significant mental burden on both sides. Among healthcare professionals, mental burden appears to arise primarily from the resource-intensive demands of endometriosis management, whereas among patients it is driven more by the need to take an active role in their own care to compensate for insufficient information provided by physicians. Conclusion: In this study, we highlighted the ambiguities surrounding the concept of therapeutic efficacy of hormonal therapies and collected several factors to try to improve shared-decision-making process in the management of endometriosis. This is designed to help us create a shared decision-making tool in the near future.

Background: Nursing education in conflict-affected settings faces significant disruptions that compromise the preparation of a competent and resilient workforce. In regions such as Iraq, prolonged instability, resource constraints, and fragmented health systems challenge traditional educational models, necessitating innovative and context-responsive approaches to ensure continuity, quality, and equity in nursing training. Purpose: This study aimed to explore innovative strategies in nursing education within conflict-affected settings and to examine their implications for leadership development, health policy reform, and the advancement of health equity. Methods: A cross-sectional descriptive study was conducted among undergraduate nursing students across selected universities in the Nineveh Governorate, Iraq, during the 2025-2026 academic year. Data were collected using a structured, self-administered questionnaire designed to assess students educational experiences, engagement with digital learning approaches, perceived barriers, and attitudes toward innovation in nursing education. The instrument captured multiple dimensions of the learning environment, including access to educational resources, institutional support, and exposure to blended and technology-enhanced learning. Descriptive and inferential statistical analyses were performed using SPSS (version 28), including frequency distributions, chi-square tests, and binary logistic regression modeling to identify key predictors of positive educational outcomes, such as engagement, satisfaction, and perceived clinical readiness. Results: The findings indicate that, although students demonstrated a high level of motivation to engage with innovative learning approaches, notable gaps remained in access to digital resources, faculty preparedness, and institutional support. A majority of participants reported engagement with blended and technology-enhanced learning, which was significantly associated with higher levels of engagement, improved critical thinking, and greater perceived clinical readiness (p < 0.001). Multivariable analysis identified institutional support, digital learning access, and learner-centered teaching strategies as significant predictors of positive educational outcomes. Students with access to digital learning resources and supportive educational environments were more likely to report higher levels of satisfaction and competence. Conclusions: Innovating nursing education in conflict-affected settings is essential to building a resilient and future-ready nursing workforce. Integrating digital technologies, flexible learning models, and competency-based approaches can enhance educational outcomes despite contextual constraints. Implications for Nursing Practice and Policy: Strategic investment in nursing education infrastructure, faculty development, and digital transformation is critical to strengthening health systems in fragile contexts. Policymakers and academic leaders must prioritize inclusive, scalable, and sustainable educational reforms to promote health equity and empower nurses as key agents of system-level change.

Care workers are central to health systems and the broader care economy, but they often lack the legal protections afforded to other workers. Furthermore, there currently exists no single legal definition of "care worker" under any binding or non-binding international legal instrument. Drawing on the WHO Global Health and Care Worker Compact, we analyzed whether national laws and policies in 10 countries protect care workers. Using comparative legal methods and primary source legal and policy documents, we evaluated both care worker coverage and alignment with four indicators: guaranteed access to protective equipment, protection against discrimination on internationally recognized grounds, unemployment insurance, and the right to join independent unions. We reviewed 43 laws and policies and found that 56% fully or partially met the relevant indicator criteria. The United Kingdom was the only country meeting all four indicators. Overall, we found while many countries recognize these protections in law, care workers are often left outside their coverage, underscoring the need for clearer legal recognition and more inclusive worker protections.

Background: Despite significant advancements in obstetric care, the incidence of preeclampsia remains a substantial public health challenge, and effective strategies to prevent the disease progression remain limited, particularly in low-resource settings. N-acetylcysteine (NAC), an antioxidant and glutathione precursor, has demonstrated anti-inflammatory and vasodilatory effects, making it a promising candidate for repurposing. However, robust evidence from well-powered randomized controlled trials is lacking. Objective: This study will evaluate the impact of NAC on the time-to-disease progression in pregnant women with early-onset preeclampsia in Lagos, Nigeria. Methods: This is the study protocol for a proof-of-concept, double-blind, randomized, controlled trial to be conducted between April 2026 to July 2028 at the maternity units of the two teaching hospitals in Lagos, Nigeria. At baseline, n=153 sexually active women aged 18 years or older diagnosed with early-onset preeclampsia at 24 to 34 weeks gestation will be randomised to receive either daily oral tablet containing 600 mg of NAC or a placebo tablet that is matched for appearance and the dosing regimen in addition to standard antenatal care from diagnosis (randomisation) until either 34 weeks gestation or delivery, whichever comes first. The primary endpoint is the time-to-progression (in days) of early-onset preeclampsia to severe disease. The data analysis will be conducted on an intention-to-treat basis. Kaplan-Meier estimates with a Log-rank test will be used to calculate and compare the time-to-disease progression for the treatment groups, while Cox proportional hazard models with a backwards conditional method will be used to compare the primary endpoint between the treatment arms while adjusting for other covariates for precision using hazard ratios (HRs) and 95% confidence intervals (95%CIs). Subgroup analyses will also be performed to assess the differential effects of significant covariates on the impact of NAC on disease progression. Statistical significance will be reported as P<0.05. Discussion: This study will evaluate the efficacy of daily oral NAC compared to placebo in treating pregnant women with early-onset preeclampsia. If proven effective, NAC could offer a safe, affordable, and scalable intervention to reduce the burden of preeclampsia, particularly in resource-constrained settings.

Background: Large Language Models (LLMs) have demonstrated strong performance in medical question-answering tasks, highlighting their potential for clinical decision support and medical education. However, their effectiveness in subspecialty areas such as nephrology remains underexplored. In this study, we assess the performance of open-source LLMs in answering multiple-choice questions from the Nephrology Self-Assessment Program (NephSAP) to better understand their capabilities and limitations within this specialized clinical domain. Methods: We evaluated the performance of five open-source large language models (LLMs): PodGPT which a podcast-pretrained model focused on STEMM disciplines, Llama 3.2-11B, Mistral-7B-Instruct-v0.2, Falcon3-10B-Instruct, and Gemma-2-9B-it. Each model was tested on its ability to answer multiple-choice questions derived from the NephSAP. Model performance was quantified using accuracy, defined as the proportion of correctly answered questions. In addition, the quality of the models explanatory responses was assessed using several natural language processing (NLP) metrics: Bilingual Evaluation Understudy (BLEU), Word Error Rate (WER), cosine similarity, and Flesch-Kincaid Grade Level (FKGL). For qualitative analysis, three board-certified nephrologists reviewed 40 randomly selected model responses to identify factual and clinical reasoning errors, with performance summarized as average error ratios based on the proportion of error-associated words per response. Results: Among the evaluated models, PodGPT achieved the highest accuracy (64.77%), whereas Llama showed the lowest performance with an accuracy of 45.08%. Qualitative analysis showed that PodGPT had the lowest factual error rate (0.017), while Llama and Falcon achieved the lowest reasoning error rates (0.038). Conclusions: This study highlights the importance of STEMM-based training to enhance the reasoning capabilities and reliability of LLMs in clinical contexts, supporting the development of more effective AI-driven decision-support tools in nephrology and other medical specialties.

Purpose: This study aimed to examine the effects of formative and summative assessments on college students tennis performance and basic psychological needs. Methods: A total of 128 undergraduate students (64 males, 64 females; Mage = 19.22, SD = 0.91) participated in this study. Participants were cluster-randomized to either a formative assessment group (n = 64) or a summative assessment group (n = 64). The formative assessment intervention involved setting personalized learning goals and success criteria, administering periodic tests, and providing process-oriented and individualized feedback. The summative assessment intervention involved setting uniform goals for all students, offering instructor feedback only on common problems, and requiring students to practice independently after class without personalized guidance. Both interventions were implemented over 10 weeks, with one 90-minute session each week. Tennis skills and basic psychological needs (i.e., autonomy, competence, and relatedness) were assessed before and after the intervention. Tennis skills were reassessed 1 week after the intervention. Two-way mixed-effects analysis of variance (ANOVA) was used to examine the impact of group, time, and their interaction on tennis skills and basic psychological needs. Results: The results showed that the interaction between group and time was significant for all of the outcome variables. Simple effects analyses indicated that, at pre-test, the two groups did not differ significantly in tennis performance or in satisfaction of autonomy, competence, and relatedness (p > 0.05). At post-intervention, the formative assessment group demonstrated significantly better performance than the summative assessment group in tennis skills (MD = 3.50, 95% CI = [1.303, 5.697], p = 0.002), autonomy (MD = 2.44, 95% CI = [1.816, 3.059], p < 0.001), relatedness (MD = 1.33, 95% CI = [0.679, 1.977], p < 0.001), and competence (MD = 1.75, 95% CI = [1.046, 2.454], p < 0.001). At the 1-week follow-up session, the formative assessment group also showed significantly better tennis performance than the summative assessment group (MD = 6.81, 95% CI = [4.667, 8.958], p < 0.001). Conclusion: Formative assessment was more effective than summative assessment in improving college students tennis performance and satisfying their basic psychological needs. These findings suggest that incorporating personalized goals, process-oriented evaluation, and individualized feedback into tennis instruction could promote both skill development and psychological outcomes in college physical education.

Background Cutaneous leishmaniasis (CL) is highly prevalent in Ethiopia, including the Tigray region. However, there is a dearth of information on the levels of knowledge, attitude, and health seeking behavior among the communities in CL-endemic areas of Tigray region, northern Ethiopia. Objective This study aimed to investigate CL-related knowledge, attitude, treatment-seeking and prevention practices in disease-endemic areas of Tigray. Methods Between November and December 2022, a cross-sectional survey was conducted among communities living in seven districts of Tigray. A mixed sampling method was implemented. Data were collected using a pre-tested structured questionnaire and analyzed using SPSS 25 (IBM, Chicago). Results A total of 512 participants were included. Overall, 43%, 36% and 34% of participants had a good level of knowledge, a favorable attitude and a good treatment-seeking and prevention practices towards CL, respectively. However, nearly all participants did not know about CL transmission, about 25% perceived CL to be genetically acquired and about 67% believed it to be stigmatizing. Traditional medication was the preferred option over modern treatment for 63.3%. Rural dwelling participants (AOR = 1.60; 95% CI: 1.00-2.57) and participants living in households with CL episode (AOR = 10.19; 95% CI: 6.36-16.30) had good knowledge towards the disease. However, urban/ semi-urban residents (AOR = 2.17; 95% CI: 1.42-3.31) had favorable attitude towards CL. Gender (AOR = 1.49; 95% CI: 1.01-2.22) and education level (AOR = 0.39; 95% CI: 0.24-0.62) were significantly associated with treatment-seeking and prevention practices. Participants living in households with CL episode (AOR = 2.99; 95% CI: 1.96-4.57) had good treatment-seeking and prevention practices. Conclusion In this study, over one half of participants had poor knowledge about CL, nearly two-third of them had unfavorable attitude towards the disease and two-third of them had poor treatment-seeking and prevention practices. Residence and previous CL episode in households were determinants of respondents knowledge about CL and their attitude towards the disease. Level of education and living in households with CL episode were determinants of participants treatment-seeking and prevention practices. These findings support for an integrated intervention through health education focusing on CL transmission and preventive measures.

Background Therapeutic empathy improves patient and practitioner outcomes, yet existing measures are often lengthy, conceptually inconsistent, and cannot be easily compared across respondent groups. Brief, universal measures (usable by patients, practitioners, students, and observers) are lacking. We therefore developed a universal single-item scale and conducted psychometric testing of the patient-reported version. Methods Following best-practice, we used a three-phase approach: (1) item development; (2) pre-testing the scale by obtaining expert panel feedback (n=9) and conducting cognitive interviews with stakeholders (n=35); and (3) scale validation in an international patient sample (n=521) assessing convergent, discriminant, and known-groups validity. Validation involved assessing correlations with the Consultation and Relational Empathy (CARE) measure and clinical neutrality measure, and by assessing differences in scores by patient ethnicity. Results We developed two versions (pictorial and text-based) of each scale. Expert feedback and cognitive interviews confirmed content and face validity. Pictorial and text-based versions showed high convergent validity with the CARE measure (r=0.761 and r=0.838, both p<0.001), and discriminant validity with a clinical neutrality measure (r=0.131 and r=0.139, p=0.003 and p=0.001, respectively). Correlations with the CARE measure remained high (r>0.70) and statistically significant (p<0.001) across patient gender, ethnicity, and practitioner type. Ethnic minority patients rated practitioner empathy lower than White patients (pictorial p=0.057; text-based p=0.033), demonstrating known-groups validity. Patients rated doctors' empathy higher than other healthcare practitioners' (p=0.001 for both pictorial and text-based); there were no significant differences in empathy scores by patient gender. Conclusions We developed the first universal single-item therapeutic empathy measure and demonstrated validity for the patient-reported versions. The scale is brief, accessible, and applicable to clinical practice, education, and research. Further research should validate practitioner-, student-, and observer-reported versions, and assess predictive and cross-cultural validity. This robust tool can support patient-reported routine measurement of therapeutic empathy and contribute to improving patient and practitioner outcomes.

PurposeThis study examined the association between traditional physical practice participation and vision-related quality of life among junior secondary school students and tested the mediating roles of exercise self-efficacy and visual function anomalies within a serial mediation framework. MethodsA four-wave time-lagged survey was conducted among 1,579 students in Grades 7-9 from schools implementing traditional physical practice activities. Variables were assessed at two-week intervals. Mediation effects were tested using the bias-corrected percentile bootstrap method with 5,000 resamples. ResultsThe total effect of traditional physical practice participation on vision-related quality of life was significant ({beta} = 0.591, p < .001). After including the mediators, the direct effect remained significant ({beta} = 0.404, 95% CI [0.348, 0.457]), accounting for 68.36% of the total effect. The total indirect effect was significant ({beta} = 0.187, 95% CI [0.160, 0.218]), representing 31.64% of the total effect. The indirect effect via exercise self-efficacy was significant ({beta} = 0.088, 95% CI [0.068, 0.112], 14.89%), as was the indirect effect via visual function anomalies ({beta} = 0.065, 95% CI [0.048, 0.086], 11.00%). The serial mediation pathway through exercise self-efficacy and visual function anomalies was also significant ({beta} = 0.034, 95% CI [0.025, 0.045], 5.75%). All confidence intervals excluded zero, supporting partial mediation. ConclusionTraditional physical practice participation was associated with vision-related quality of life both directly and indirectly through exercise self-efficacy and visual function anomalies, including a significant serial mediation pathway. The findings highlight the combined psychological and functional mechanisms underlying adolescents vision-related quality of life.

Background: Generative artificial intelligence (GenAI) chatbots have shown utility in assisting with various research tasks. Traditional, complementary, and integrative medicine (TCIM) is a patient-centric approach that emphasizes holistic well-being. The integration of TCIM and GenAI presents numerous key opportunities. However, TCIM researchers' attitudes toward GenAI tools remain less understood. This large-scale, international cross-sectional survey aimed to elucidate the attitudes and perceptions of TCIM researchers regarding the use of GenAI chatbots in the scientific process. Methods: A search strategy in Ovid MEDLINE identified corresponding authors who were TCIM researchers. Eligible authors were invited to complete an anonymous online survey administered via SurveyMonkey. The survey included questions on socio-demographic characteristics, familiarity with GenAI chatbots, and perceived benefits and challenges of using GenAI chatbots. Results were analysed using descriptive statistics and thematic content analysis. Results: The survey received 716 responses. Most respondents reported familiarity with GenAI chatbots (58.08%) and viewed them as very important to the future of scientific research (54.37%). The most acknowledged benefits included workload reduction (74.07%) and increased efficiency in data analysis/experimentation (71.14%). The most frequently reported challenges involved bias, errors, and limitations. More than half of the respondents (57.02%) expressed a need for training to use GenAI chatbots in the scientific process, alongside an interest in receiving training (72.07%). However, 43.67% indicated that their institutions did not offer these programs. Discussion: By developing a deeper understanding of TCIM researchers' perspectives, future AI applications in this field can be more informed, and guide future policies and collaboration among researchers.
